    Hi all!

    I am trying to find a good plant species to use in a freshwater refugium. I am looking for a species that does not require substrate (can be left free-floating in refugium or simply weighted down/tied to rock), and that does a good job absorbing large amounts of nutrients from the water column. Refugium passes relatively large amount of water (450 gph), so looking for a species that doesn't mind water flow.

    I have dedicated Aquaray GroBeam LED (6500K) on the refugium, and direct CO2 injection (diffuser in refugium).

    The refugium is an Aqueon ProFlex Model II, in case that matters.

    Water conditions:
    - 78 degrees F
    - 9 dGH
    - 5 dKH
    - 7 pH

    I am currently using hornwort, but having difficulties keeping it alive, as I have been advised that the flow rate is too high, so I am looking for alternatives.

    Any suggestions would be appreciated!

    I'm working on a similar idea and was thinking using floaters in a sump, which would not work for you with high current. Curious how this works out for you.

    Floating plants are the best, or emergent plants.

    Thanks, Tom ... is there one or two in particular you would recommend for high flow refugium?
